number of moles present = molar mass (g)
1 mol
The molar mass is the sum of the atomic masses present in a compound. Be sure to take quantity into acount.
For intance...
the molar mass of H2O is 18.02 because 1.01+1.01+16=18.02
Multiply the number of moles by the molecular weight
moles divided by grams gives the inverse of molecular weight, which i have never come across.
number of moles = mass / molecular mass. molecular mass is grams per mole
divide the mmoles by 1000 to get moles. then multiply by molecular weight
Multiply the number of moles by the relative molecular mass.
mass of 2 moles of water
= 2 mol x 18.0 g/mol
= 36 g
Multiply by the molecular weight. You have to make sure this is in grams per mole (or milligrams/millimole, same thing)
For converting any substance in moles to grams:-
Grams= No. of moles x Atomic or molecular mass.
At STP1mol O2 = 22.4L1mol O2 = 6.022 x 1023 molecules O222.4L O2 = 6.022 x 1023 molecules O2Convert liters O2 to moles O23.36L O2 X (6.022 x 1023 molecules O2/22.4L O2) = 9.03 x 1022 molecules O2
You haven't stated the compound or molecular weight. The formula you need is the number of moles = mass / molecular mass. If you have millimoles, multiplying by molecular weight will convert to milligrams.
Multiple the moles of K2SO4 by the molecular weight of 174.2592 grams. That should equal 210.85 grams.
There are 200 grams in 200 grams.
About 907.2 grams.
100 millimoles is 0.1 moles. To convert moles to grams, you need to multiply by the molecular weight, in this case, 194.22g/mol. 0.1*194.22 is 19.422 grams.
Because the formula for calculating moles is dividing grams by the molecular weight. The molecular weight for glucose is 180. grams to moles is also the same as milligrams to millimoles.
For this you need the atomic mass of Ca. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel.125 grams Ca / (40.1 grams) = 3.12 moles Ca
The molecular weight of water is 18g/mol. There are 0.00325 moles in 3.25 millimoles. 0.00325*18 is 0.0585 grams. This is 0.0000585 kilograms.
Mol wt of C6H12O6 = 6*12 + 1*12 + 16*6 = 72+12+96 = 180 This implies that 180 grams of the compound is equivalent to 1 mole 1 mole = 180 grams => 1 millimole = 180 milligrams => 8.57 millimoles = 180*8.57= 1542.6 milligrams = 1.5426 grams
fo potassium 60 mEq K = 60 millimoles 39.1 grams per mole ( 0.060moles) = 2.346 grams =2346 mg
The molar mass of glucose is 180,16 grams.180,16 g------------1 mol35 g------------------xX = 0,194 moles or 194 millimoles
There are 1000 millimoles in a mole. So you need to divide by 1000 here. 1250 millimoles / 1000 is 1.25 moles.
Millimole is 1000th of a mole which is 10^-3
Millimoles are a unit of measurement based of mole, which measures the amount of substance in something that has an equal number of atoms and elementary entities. Millimoles are calculated by multiplying the amount of moles by 1,000.

You need to divide by 1000 here. This is because there are 1000 millimoles in a mole. 2.55/1000 gives you 0.00255 moles.
